I'm leaving this here so I I remember to watch them but you might also find them handy. Çingleton is a small (read "exclusive") conference in Montreal. The speakers are pretty much all people I like to pay attention to. One day, maybe I will get to go.
In the future, these videos will probably move from this page and be available via their Vimeo account. For reference, the 2011 videos are available on Vimeo now.
